Former Dallas Cowboys superstar DeMarco Murray appears to still be making waves despite moving from the Tony Romo team. Following his troubled stint with the Philadelphia Eagles, where he reportedly got into disagreements with now San Francisco 49ers head coach Chip Kelly, the running back was sent to the Tennessee Titans in a massive NFL trade deal. However, reports claim that his new NFL team is once again experiencing issues with him - a problem that is said to become more apparent in light of the promising performance of Heisman Trophy winner Derrick Henry.

DeMarco Murray was initially thought to be a key piece in the Philadelphia Eagles roster. However, his move to the Sam Bradford team proved to be disastrous. In fact, Murray was rumored to have contemplated going back to his beloved Dallas Cowboys last NFL season due to the problematic coaching of Chip Kelly. However, the lucrative contract of the running back proved to be a huge hindrance in his desired reunion with Dez Bryant.

It was the Tennessee Titans that eventually decided to splurge on Murray in an effort to boost their team's chances of dominating the gridiron. However, rumors are now rife that the former Dallas Cowboys running back is causing problems in the roster. Moreover, speculations note that the veteran star is feeling insecure over the entry of Derrick Henry.

Does this mean that the Tennessee Titans now regret their move to spend a ton of cash on the ex Dallas Cowboys superstar? Would a DeMarco Murray trade happen soon again? Is Derrick Henry ready to take over from the superstar running back by the start of the regular NFL season?

The answers to all these appear to be in the negative. In fact, the Tennessee Titans could not stop singing praises for DeMarco Murray - a situation so different from the reception he received from the Philadelphia Eagles last NFL season.

"He's a coach's dream,'' shared Sylvester Croom of DeMarco Murray. The Tennessee Titans running back coach noted that the former Dallas Cowboys star showed impressive leadership skills and remarkable workmanship in the gridiron during their training sessions this NFL offseason.

Meanwhile, Croom revealed that the performance of Derrick Henry shows flashes of his potential to become a remarkable NFL superstar. While the Tennessee Titans coach admitted that the Heisman Trophy winner has yet to toughen up mentally to succeed in the NFL, the rookie's physical strength is undeniably notable.

"From a physical standpoint, his football talent is obvious,'' said Croom of Derrick Henry. He added, "Now, the mental toughness, the mental discipline, how to truly be a professional football player -- that is the key and it will determine how much success he is going to have and how much he'll be able to help our football team. The talent is there, but until a rookie goes through the first season, he really doesn't know what it takes to be a pro at this level."
